And yes, the stream of controlled Windows 8 leaks continues. This time around, Thurrot and Rivera have published a number of screenshots from Windows 8's brand-new tablet user interface, and surprise surprise, its built on Metro, the same design language that underpins Windows Phone 7. Windows 8 will also include its own PDF reader, Modern Reader, which also happens to be the first application packaged in Microsoft's new AppX format. Update: Long Zheng has some technical details on AppX, including this little tidbit: "The extensive list of properties signifies the comprehensive scope of this system to be the ideal deployment strategy for 'applications', in all essence of the word. In fact, the AppX format is universal enough so it appears to work for everything from native Win32 applications to framework-based applications and even *gasp* web applications. Games are also supported."

You're right, and it sounds like it'll still support Win32. I guess when I heard that it was supposed to be like Window Phone 7 application packages I interpreted it to mean like the Windows Phone Application Platform.
